Farpoint Group
Aerohive has introduced a wireless-LAN architecture that runs counter to the centralized-architecture model that has dominated thinking in the industry in 2002. But Aerohive has introduced a number of key features that improve reliability and cost-effectiveness, and demonstrate that the level of innovation in the wireless-LAN space remains high - and also that there is no clear trend in WLAN architecture.

Farpoint Group: Unified Networks - The Best Tool for the Job
There has been significant discussion of how wireless might in fact replace wire over time. As it turns out, wireless actually motivates the need for wire in many cases, and there are some applications that will likely never go wireless. This White Paper provides advice to the enterprise on the further deployment of wire, and also introduces the concept of a unified network with significant functional overlap between wired and wireless.

Farpoint Group: 802.11n - Implications for the Enterprise
802.11n is the latest in a long line of wireless-LAN standards, and the one that is likely to be the most important since the original 802.11 standard in 1997. With improved throughput and rate-vs.-range performance, products now appearing in the marketplace, and many other features, .11n is a sooner-rather-than-later option for enterprise-class deployments. Moreover, .11n will put greater emphasis on key architectural alternatives in differing .11n implementations.

Farpoint Group: Evaluating Interference in Wireless LANs: Recommended Practice
Radio interference remains a core concern among wireless LAN (WLAN) users, network administrators, and operations staff alike. After all, the potential for interference is a fact of life in the unlicensed bands where WLANs operate, and, even worse, it is often very difficult to evaluate the effects of interference on a particular wireless-LAN (WLAN) installation at any given moment in time. In this paper, Farpoint Group presents a core set of recommendations for evaluating and dealing with the interference challenge.

Farpoint Group: The Effects of Interference on General WLAN Traffic
Interference can severely degrade the performance of wireless LANs, finds a new technical note from Farpoint Group. Just how bad is it? Consider the throughput reductions caused by these common devices: Microwave oven - 62%; another wireless LAN - 89%; Bluetooth headset - 20%; cordless phone - 100%. As wireless LANs proliferate and become the default connectivity for essentially all users in enterprise environments (and beyond), the interference issue will become even more acute.

Farpoint Group: Gateways for Mobile WiMAX
While the emphasis in wireless is naturally on radio, the remainder of the value chain in any network implementation (wired or wireless) can have a profound effect on the results obtained and the quality of services offered. This White Paper examines the role that Access Service Network(ASN) gateways will play in WiMAX system deployments, and why the selectionof the proper mix of gateway features is essential to optimizing both network responsiveness and carrier revenues.

Farpoint Group: The All-Wireless Enterprise
This Technical Note reports on a series of tests conducted on an enterprise-class WLAN system, examining both data and voice performance for a large number of clients. We discovered that it is possible, even in advance of 802.11n, to deploy mixed voice/data WLANs that can indeed provide primary and even default access for a large number of user with wireline-class results.

Farpoint Group: The Effects of Interference on VoFi Traffic
Interference can have a devastating effect on the quality of VoFi connections, and with the percentage of voice traffic on the LAN expected to grow dramatically over the next few years, interference is rapidly becoming a challenge that enterprise IT managers must address. In this technical note, Farpoint Group offers advice for mitigating the interference threat.

Farpoint Group: Interference and Metro-Scale Wi-Fi Mesh Networks
With metro-scale Wi-Fi poised to become common and even ubiquitous, two key questions arise with respect to radio interference. First, will residential and enterprise Wi-Fi systems potentially degrade metro-scale Wi-Fi network performance? Second, and far more interesting, will metro-scale Wi-Fi networks cause interference to other unrelated Wi-Fi systems located nearby? In fact, it is likely that both forms of interference will occur, says Farpoint Group, and enterprise Wi-Fi networks will need to respond to the challenge.

Farpoint Group: Mesh Architecture - Applications and ROI
Metro-scale Wi-Fi mesh deployments are increasing, enabling a broad range of applications that place an equally broad array of demands on the mesh.This white paper discusses applications requirements and the key features that mesh implementations require to support them. We also discuss how specific mesh architectures affect total cost of ownership and return on investment.

Farpoint Group: Residential media distribution: The wireless alternative
This document explores another multi-antenna direction, based on an approach known as digital beamforming. Is this MIMO? Well, it uses multiple antennas for transmitting, so you be the judge. Considering the number of firms now working in the space, and the surprisingly large number of multi-antenna products already available, the debate is sure to rage on.

Farpoint Group: Open-Access Wireless Networks
A clear trend - now embodied in FCC regulations - towards making future wide-area wireless networks open to a broad range of compatible subscriber units, even those not sold by the carrier, is now evident. Moreover, theuse of IP as the transport mechanism in future wireless networks introduces the possibility of combining previously separate networks - such as those intended for commercial use and those reserved for public-safety applications - into a single network. These trends have important implications for the future of wireless.

Farpoint Group: The Invisible Threat: Interference and Wireless LANs
Interference is a fact of life in the unlicensed bands used by wireless LANs (WLANs) and is an increasing challenge in all WLAN environments â enterprise, metro-scale Wi-Fi meshes, and residential. As the number of unlicensed devices grows and as ever more mission-critical applications are deployed on WLANs, interference represents a challenge that must be addressed.
